STEERING AND WAR'PING GEAR.

SPECIFICATION forming part of Letters Patent N o. 639,939, dated December 26, 1,899.

Application tiled November 3, 1898. Serial No, 695,362. (No model.)

"To all whom it may concern:

Be it known that I, ROBERT RICHARDSON, engineer, residing at 16 Jamieson street, Govanhill, in the city of Glasgow, Scotland, have invented certain new and useful Improvementsin Steering and Warping Gear,of which the following is a specification.

This invention relates to steering and warpconstruction of some of the parts,while readily permitting of steering or warping by steam or by hand power.

The invention is illustrated by the accompanying drawings, Figure 1 being a vertical section of the improved steering and warping gear, and Fig. 2 a diagrammatic plan of a portion of the same.

In carrying out the invention I key upon the lower end of the usual vertical drivingspindle A a toothed wheel B and gear said wheel to three or any convenient number of toothed wheels O, carried upon studs C' in the separate plate-cover D of the'chain-drum casing D'. These wheels C, which in turn gear with the internal teeth E' on the chaindrum or gypsy-wheel E, are driven by the toothed wheel B on the vertical spindle A, which spindle receives its motion from connections hereinafter described. I form a footstep bearing F for the lower end of the shaft which drives the chain-drum in a boss G' on the bed-plate G, said boss G' forming the stud upon which the boss of the chain-drum E turns. Above the toothed wheel B on the lower end of the vertical shaft A and on a sleeve H', turning freely thereon, I form or secure the usual worm-wheel H, which gears with the worm I on the power-shaft I'. sleeve H' is keyed to the boss J 'of the lower portion of the capstan J and is centered in the top cover D2 of the casing D', the capstan J being made in two parts capable of separate movement, but normally secured together by a bolt K, the vertical shaft A being carried up to near the upper face of the capstan. On the upper end of the vertical shaft a disk L is secured, through a hole in which a bolt M is passed to a like hole J 2 in the capstan J when it is desired to carry the capstan J around with the vertical shaft A.

ThisA The steering-gear is driven by a pair of horizontal steam reversing-engines of common type used in steering-gear, the engines preferably being fore and aft, one to port and one to starboard.

When it is desired to steer by steam-power, the bolt K, engaging both portions of the capstan J, and the bolt M, engaging the capstan and the disk L on the upper end of the vertical shaft A, are left in position, and the power for turning the chain-drum E is thus transmitted through the worm-wheel I and the capstan J to the vertical shaft A.

When it is desired to warp by steam-power, the pin M, engaging the capstan J and the disk L on the vertical shaft A, is withdrawn, the pin M being transferred to a hole in the plate-cover D of the chain-drum casing D', where it engages with one of a series of holes E2in the chain-drum E to prevent jerking of drum E, and the capstan J alone is turned by means of the worm-wheel H, whose sleeve H is keyed to the boss J of the capstan J. When warping by hand, both pins are withdrawn.

Should it be desirable at any time to steer by hand, the bolt engaging the capstan J and the disk L on the vertical shaft A is left in position; but the bolt K, securing the lower and upper portions of the capstan J together, is withdrawn, the power for turning the chaindrum E being transmitted through the capstan J and disk L by the capstan-bars, which ship in the upper half of capstan J.

The usual handing wheel-gear is provided for steering from the bridge, and on the automatic gear-spindle N a toothed wheel N' is secured, which gears with a pinion O on a stud O', carried in the plate-cover D of the chain-drum casing D', said pinion O or a second pinion secured to it being geared to the internal teeth or, as shown, gearing with eX- ternal teeth on the chain-drum E, so that the handing-gear is always in position. A handwheel on the top of the automatic gear-spindle N allows of the controllingvalve being moved in either direction for working the capstan J by steam, no disconnecting-gear being used.

As an alternative the pinions 0, instead of being carried on studs in the cover D of the IOO esaee chain-drum casing D and gearing with internal teeth on the chain-drum E, may be carried in studs upon the chain-drum and gear with teeth upon the chain-drum casing.

The capstan J may be dispensed with, the other parts alone being used as a steeringgear, in which case the worm-wheel H instead of being loose upon the central shaft is keyed thereto.

Having now described the invention, what I claim, and desire to secure by Letters Patent, is-

1. The combined steering and warping gear comprising a drum-casing, a chain-drum rotatable in said casing, one of said parts being provided with teeth, toothed pinions Within said casing and gearing with said mentioned teeth, a rotatable spindle provided with a pinion gearing with said toothed pinions, a wor1n- Wheel rotatable on said spindle, a worin-shaft for driving the Worm-Wheel, a capstan made in parts separately connected together and having one part connected to the worm-Wheel to turn therewith, and a disk connected to the spindle to turn therewith and separably connected to one part of the capstan, substantially as described.

2. The combined steering and warping gear composed of a drum-casing having a central boss, a chain-drum centered loosely upon said boss and formed with gear-teeth, toothed pinions supported from the drum-casing and gearing with the drum, a rotatable spindle provided with a pinion gearing with said toothed pinions, a worm-Wheel rotatable on said spindle, a Worm-shaft for driving the Worm-Wheel, a capstan made in parts separably connected together and having one part connected to the Worin-Wheel to turn therewith, and a disk connected to the spindle to turn therewith and separably connected to one part of the capstan, substantially as described.

In Witness whereof I have hereunto set my hand in presence of two Witnesses.

ROBERT RICHARDSON.
